About Batteries

If you're operating the JUNO-Gi on batteries, you'll need
eight rechargeable Ni-MH batteries (AA, HR6). The battery
life will depend on the specifications of the battery and
on the conditions of use, but for continuous use, will be
approximately 3 hours (approximately 2 hours if USB
memory is connected).
About rechargeable batteries
When using rechargeable batteries, the battery lifespan
will normally become shorter with each recharge cycle.
If the batteries run down soon after being recharged, it's
time to replace them.

Installing Batteries

1. Switch off the JUNO-Gi's power (p. 16).
2. Remove the cover of the battery compartment located on
the JUNO-Gi's bottom panel.
While pressing the tabs of the cover, lift the cover up and remove it.
3. Insert the batteries into the battery compartment.
Make sure to observe the correct polarity (+/– orientation) for each
battery when inserting it.
4. Replace the battery compartment cover.
* When turning the unit upside-down, get a bunch of newspapers or
magazines, and place them under the four corners or at both ends to prevent
damage to the buttons and controls. Also, you should try to orient the unit so
no buttons or controls get damaged.
* When turning the unit upside-down, handle with care to avoid dropping it, or
allowing it to fall or tip over.
Note the following when using batteries
• Do not use alkaline batteries or carbon-zinc batteries.
• The use of an AC adaptor is recommended as the unit's power consumption is relatively high. Should you prefer to use batteries, please use the
rechargeable Ni-MH type.
• When installing or replacing batteries, always turn off the power on this unit and disconnect any other devices you may have connected. This way,
you can prevent malfunction and/or damage to speakers or other devices.
• We recommend that you keep batteries installed in the unit even though you'll be powering it with the AC adaptor. That way, you'll be able to
continue a performance even if the cord of the AC adaptor gets accidently disconnected from the unit.
• Do not allow any objects (e.g., flammable material, coins, pins); or liquids of any kind (water, soft drinks, etc.) to penetrate the unit.
• If used improperly, batteries may explode or leak and cause damage or injury. In the interest of safety, please read and observe the following
precautions.
• Carefully follow the installation instructions for batteries, and make sure you observe the correct polarity.
• Avoid using new batteries together with used ones. In addition, avoid mixing different types of batteries.
• Remove the batteries whenever the unit is to remain unused for an extended period of time.
• If a battery has leaked, use a soft piece of cloth or paper towel to wipe all remnants of the discharge from the battery compartment. Then
install new batteries. To avoid inflammation of the skin, make sure that none of the battery discharge gets onto your hands or skin. Exercise
the utmost caution so that none of the discharge gets near your eyes. Immediately rinse the affected area with running water if any of the
discharge has entered the eyes.
• Never keep batteries together with metallic objects such as ballpoint pens, necklaces, hairpins, etc.

When to Replace the Batteries (BATTERY
Indicator)
The BATTERY indicator shows the state of the
batteries.
Indication Explanation
Unlit Batteries are not installed.
Operating on batteries, with sufficient battery power
Green
remaining.
Batteries have run low. We recommend that you replace the
Red
batteries.
Batteries are nearly depleted. Stop use, and recharge the
batteries. If you continue using the JUNO-Gi when the
Blinking red
indicator is blinking red, the indication "Battery Low!" will
appear, and further operation will not be possible.
* The remaining battery indication is an approximation.
MEMO
• In order to reduce battery consumption, you can turn off the
display backlight when it's not required. Refer to "Turning the
Display Backlight On/Off" (p. 17).
• The System setting "Power Save Mode" (p. 80) lets you choose to turn
off the backlight when no operation has been performed for a
certain length of time. (With the factory settings, the backlight will
dim after five minutes.)
• The System setting "Auto Power Off" (p. 80) lets you choose to turn off
the power automatically when no operation has been performed
for a certain length of time. (With the factory settings, the power
will turn off after 240 minutes.)

Removing Batteries

To remove the batteries, switch off the JUNO-Gi's power, remove the
battery case cover, and remove the batteries as described in "Installing
